Sorry for the trouble. I am Vineeth and I am from the Norton Support team.
You can use the following page to download and install the Norton product:
Or you can use the Norton 360 Premier link under Norton 360 Multi device in this support article to download and install the Norton product: https://support.norton.com/sp/en/us...
